The present disclosure relates generally to bags, and more particularly to multi-handled bags and related methods of use.
The written disclosure herein describes illustrative embodiments that are non-limiting and non-exhaustive. Reference is made to certain of such illustrative embodiments that are depicted in the figures, in which:
The present disclosure relates generally to bags, and more particularly to multi-handled bags and related methods of use. In some embodiments, the multi-handled bag comprises a first wall, a second wall, a first gusset, and a second gusset, wherein the first wall, the second wall, the first gusset, and the second gusset cooperate to define at least a portion of a cavity. In some of such embodiments, the multi-handled bag further comprises a first flap comprising a first handle; a first intermediate seal disposed at a first end of the first flap, wherein the first intermediate seal consists of a single transverse seal that extends along a full width of the bag; and a first end seal that extends along only a portion of a second end of the first flap. Similarly, the multi-handled bag can also comprise a second flap comprising a second handle; a second intermediate seal disposed at a first end of the second flap, wherein the second intermediate seal consists of a single transverse seal that extends along a full width of the bag; and a second end seal that extends along only a portion of a second end of the second flap. In certain of such embodiments, the multi-handled bag is devoid of additional seals. Additional embodiments and details are further discussed below.
Embodiments of the disclosure may be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. It will be readily understood that the components of the present disclosure, as generally described and illustrated in the drawings herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments is not intended to limit the scope of the disclosure, but is merely representative of possible embodiments of the disclosure. In some cases, well-known structures, materials, or operations are not shown or described in detail. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
As shown in
In certain embodiments, the first wall 110 can be described as having a top end 114 and a bottom end 112. Likewise, the second wall 120, the first gusset 130, the second gusset 140, and/or the bag material 100 generally can also be described as having a top end and a bottom end. As used herein, directional terms, such as “front,” “rear,” “top,” “bottom,” etc., are used with respect to the orientation shown in
In various embodiments, the bag material 100 comprises a tubular structure. For example, the bag material 100 may be extruded as an elongated tubular structure. The elongated tubular structure can thereafter be cut to form smaller tubular structures (such as the structure depicted in
As shown in
With continued reference to
The various regions 152, 154, 156, 158 of the bag material 100 can be coupled in various ways. In some embodiments, for example, the walls 110, 120 at the various regions 152, 154, 156, 158 can be coupled by one or more seals. Illustrative types of seals include, but are not limited to, adhesive seals, mechanical seals (e.g., sewing, stitching, etc.), and heat seals (e.g., made with hot bar sealers, ultrasonic welding, etc.). Other types of seals and/or coupling mechanisms can also be used. In certain embodiments, the seals can also be referred to as seams.
In some embodiments, one or more of the seals are applied such that they extend along an entire or full width of the bag material 100 (e.g., from one lateral edge 116 to another lateral edge 118). In such embodiments, the seals can be referred to as transverse seals. One or more seals can also be applied across only a portion of the width of the bag material 100. In such embodiments, the seals can be referred to as partial seals. In yet further embodiments, one or more tack seals can be used.
As can be appreciated, and as further detailed herein, the seals or seams can be applied at various stages in the manufacturing process. For example, a manufacturer may apply a seal at a first intermediate region 154 prior to providing the bag to a customer or downstream user. The customer or downstream user may then fill the bag with one or more products and apply a seal at the second intermediate region 156 to enclose the one or more products in the cavity 102 of the bag. If desired, the manufacturer, customer, and/or downstream user may further apply a seal at a first and/or second end region 152, 158 (e.g., to hold the walls of the flaps 160, 162 together).
In some embodiments, the bag material 100 is coupled such that it forms a flap 160 on either end of the bag material 100. For example, the bag material 100 can be coupled at a first intermediate region 154 such that a first flap 160 is formed at one end 112 of the bag material 100. The bag material 100 can also be coupled at a second intermediate region 156 such that a second flap 162 is formed at another end 114 of the bag material 100. The flaps 160, 162 can also be described as header regions or handle regions 160, 162.
In some embodiments, a length or height of the flaps 160, 162 is defined by the location of the intermediate seals or seal regions 154, 156. For example, the length or height of the flaps 160, 162 can be described as the distance between the bag end 112, 114 and an intermediate seal or seal region 154, 156. In certain embodiments, the length or height of the flaps 160, 162 is between about 1.5 inches and about 5 inches, between about 2 inches and about 4.5 inches, between about 2.5 inches and about 4 inches, or between about 3 inches and about 3.5 inches. Other suitable lengths or heights are also contemplated.
The flaps 160, 162 can be advantageous in many ways. For example, in some embodiments, a handle is disposed in each of the flaps 160, 162 (as is shown in the embodiment of
As further shown in
Moreover, in the illustrated embodiment, an end seal 172 has also been applied at an end seal region 152. As shown in
As further shown in the illustrated embodiment, a handle 164, 166 has been disposed in each of the bag flaps 160, 162. The handles 164, 166 may be formed in various ways, such as by a laser or a blade (or other mechanical implement), or by another suitable mechanism or method. In some embodiments, the handles 164, 166 may be formed in the bag 101 by cutting one or more slits and/or apertures 168 into the bag 101. For example, one or more apertures 168 can be cut or otherwise disposed through each of the first wall 110 and the second wall.
If desired, a reinforcement member 161 can also be disposed in the flap 160, 162, and the handle 164, 166 can also be cut or otherwise disposed through the reinforcement member 161. As shown in
In some embodiments, the reinforcement members 161 may reinforce, strengthen, and/or support the handles 164, 166. For example, the reinforcement members 161 may inhibit or prevent the handles 164, 166 from tearing through a portion of the first wall 110 and/or the second wall. During use, a user may grasp the handle 164, 166 to lift or carry the bag 101. The contents of the bag 101 may be heavy such that during lifting or carrying of the bag 101 substantial pressure is applied to at least a portion of the bag 101 at or adjacent the handles 164, 166. For example, in some embodiments the bag 101 may be configured for heavy-duty applications. For instance, the bag 101 may be configured to retain one or more products like salt (e.g., salt pellets), rocks (e.g., gravel), bark, fertilizers, etc. The bag 101 may also be configured to retain at least 5 lbs, 10 lbs, 15 lbs, 20 lbs, 25 lbs, 30 lbs, 35 lbs, 40 lbs, 45 lbs, 50 lbs, or 55 lbs, or more of the product. In such embodiments, the reinforcement member 161 may act to reinforce, strengthen, and/or support the handles 164, 166, minimizing the risk of bag failure. In various embodiments, the handles 164, 166, the reinforcement member 161, and/or the handle 164, 166 in combination with the reinforcement member 161 may be substantially tear-resistant.
Various types of reinforcement members 161 can be used, including, but not limited to one or more of a tape (e.g., an adhesive tape), a film, a fabric, or a reinforcement material. The reinforcement members 161 may include a polymeric material (e.g., polyethylene, polypropylene, etc.), fibers, another suitable reinforcement material, or any combination thereof. As shown, a width and/or a height of the reinforcement members 161 can be greater than a width and/or a height of the handle 164, 166. In other words, the reinforcement members 161 may surround the handle 164, 166.
With continued reference to
Additionally, it will generally be understood that the shape and/or size of the handle 164, 166 and/or apertures 168 can vary as desired. Indeed, any variety of handles 164, 166 and/or apertures 168 can be cut or otherwise disposed on or formed in the flap 160, 162. Further, the handle 164, 166 and/or apertures 168 can be disposed in the bag 100 before or after the one or more intermediate seals are applied. The handles 160, 162 can be also cut or otherwise disposed into the bag 101 or bag material prior to sealing and/or filling the bag 101 with one or more products.
In certain embodiments, such as the illustrated embodiment, the ends 112, 114 of the bag 101 are also at least partially sealed. In further embodiments, it will be understood that the first wall 110 and second wall 120 need not be coupled (e.g., sealed) at their outermost peripheral edges. For example, at least a portion of the first and second walls 110, 120 can be coupled (e.g., sealed) at a location on the top ends 114 and/or bottom ends 112 that is inside of or adjacent to their peripheral edges, resulting in a skirt 119, 117 (or unsealed region) at the top 114 and/or bottom 112 peripheral edges of the bag 101.
As further shown in
Further, in some embodiments, the bag 101 is devoid of additional seals. For example, the bag 101 need not include seals in addition to the first intermediate seal 174, the second intermediate seal 176, the upper seal 178 (e.g., a first end seal), and the lower seal 172 (e.g., a second end seal).
Analogous to the bag 101 as described above, the bag 201 can include a first wall 210, a second wall (not depicted), a first gusset 230, and a second gusset 240. The first wall 210, second wall (not depicted), first gusset 230, and second gusset 240 can cooperate to define at least a portion of a cavity 202. The bag 201 further includes a first and second flap 260, 262, each of which is defined at least in part by an intermediate seal 274, 276. Each flap 260, 262 also includes a handle 264, 266. As shown in

Likewise, as depicted, the slit 380 can be substantially linear. In other embodiments, the slit 380 may be curved, wavy, or zig-zag shaped. Any other suitable shape can also be used. As shown, the slit 380 can also be disposed such that it is substantially parallel with the top and/or bottom ends 314, 312 of the bag 301. The slit 380 can also include a series of perforations, or can be a continuous cut out region, as desired.
Other types of handles are also contemplated. For example, handles having other shapes and/or sizes may also be used with any of the bags disclosed herein. Illustrative handles that can be used are described in U.S. Pat. No. 6,231,232, entitled “BAG WITH TEAR-RESISTANT HANDLE,” which is incorporated herein by reference in its entirety.

Any variety of materials may also be used to form the bags or the components of the bags disclosed herein. For example, in some instances, it may be desirable to select materials that are relatively stiff such that the bags are sufficiently rigid to hold or maintain their structure or conformation. It may also be desirous to form a bag that is relatively flexible.
In certain embodiments, the bags may be formed from one or more sheets (e.g., a polyolefin sheet), tube stock (e.g., polyethylene tube stock), or another suitable material. In certain embodiments, the tube stock may have a thickness between about 2 mils and about 12 mils, between about 4 mils and about 10 mils, between about 6 mils and 8 mils, or another suitable thickness. The sheet or tube stock may be one or more of a coextruded, monoextruded, single-ply, and/or multi-ply material. For example, a multi-ply material may include multiple thicknesses of the same sheet or tube stock. In another example, a multi-ply material may include different materials to provide particular characteristics, such as, but not limited to, strength, flexibility, UV resistance, and/or color. The sheet or tube stock may also be one or more of a woven, non-woven, synthetic, and/or non-synthetic material.
In some embodiments, the bags may include a single-layer film. In other embodiments, the bags may include a multi-layer film. As used herein, the term “film” refers to the material of which the bags may be formed, and may include both polymeric and paper components as disclosed herein. The term “film” includes laminate, single-layer, and multi-layer polymeric products, and may include a fiber product. The bags may also include a laminate or a coextruded material. Exemplary materials that may be used in forming the bags include polymeric materials such as polyethylene polymers and copolymers, polypropylene polymers and copolymers, polyester polymers and copolymers, and/or polyamide polymers and copolymers. Other materials are also within the scope of this disclosure.
As can be appreciated, the bags can be shorter or taller than what is depicted in
The bags provided herein may also be formed in a variety of sizes and configurations. In some instances, some variations in addition to size may exist between the smaller and larger format bags. For example, in some embodiments, larger format bags may be formed of a stiffer material. The stiffer material may aid in maintaining the bag shape and allowing the bag to stand on its own. The stiffer material also may aid in maintaining the opening in an open state, as a width of the opening can be bigger for the larger format bags. Other alterations are also possible, such as omitting or including various seams or seals and/or, where seams or seals are present, increasing or decreasing a width of each seam or seal.
Any methods disclosed herein include one or more steps or actions for performing the described method. The method steps and/or actions may be interchanged with one another. In other words, unless a specific order of steps or actions is required for proper operation of the embodiment, the order and/or use of specific steps and/or actions may be modified.
